2.Wiring Diagram
Direction for use Wiring:
1. Connect Battery B- with BMS B- firstly!
2. Connect Battery 1, Battery 2,…Battery 8 with the BMS as the picture shows.
(Please weld the wires in order and avoid pseudo solder joints.)
3. Conecte o carregador C-/Carga P- com BMS C-/P- (Use fios de tamanho maior)
4. Conecte o pólo positivo: Carregador C+/Carga P+ com Bateria B+ (Use fios de tamanho maior) .
Pay attention to make insulation.
